Description
Technical Field
[0001] The present invention relates to the field of electronic equipment structure design, and in particular to a modeling method, system and medium based on universal characteristics of electronic equipment structure. Background Art
[0002] With the increasing diversification and complexity of electronic equipment product requirements, shortened product development cycles, and intensified market competition, designers are urgently required to develop products that meet requirements, provide reliable quality, and deliver excellent performance in a short period of time. The structural design cycle impacts the overall development cycle of electronic equipment.
[0003] During the structural design of electronic equipment, there are many common, standard, and identical features and interfaces. Currently, when conducting structural design in related domestic industries, the management granularity is not fine enough, and management is only carried out at the component and whole-piece level, lacking management of these common features. Designers need to repeatedly create common features and manually mark dimensions every time they model. However, the basic operations such as points, lines, and surfaces involved in the modeling process are cumbersome and prone to errors, resulting in inefficient structural design and insufficient standardization. This problem is particularly prominent in industries such as radar that require small-batch, customized R&D. Therefore, there is an urgent need to study a convenient, efficient, and standardized modeling method for the common structural features of electronic equipment. Summary of the Invention
[0004] In order to solve the problems in the prior art of complicated, error-prone and insufficient standardization of structural design, the present application proposes a modeling method, system and medium based on the general characteristics of electronic device structure.
[0005] In a first aspect, a modeling method based on the general characteristics of electronic device structures is provided, which adopts the following technical solutions:
[0006] Build a general feature database;
[0007] According to the design task book, push the matched common feature list to the CAD platform;
[0008] On the CAD platform, the general feature database is called to perform modeling according to the general feature list.
[0009] Furthermore, the general feature database includes the following logical sub-libraries: a feature library of purchased components, a feature library of enterprise general parts, and other feature libraries;
[0010] The purchased component feature library stores the installation interface features of the purchased components;
[0011] The enterprise common parts feature library stores the repetitive structural installation features of the enterprise's internal self-made parts;
[0012] The other feature library stores common features that are not covered by the purchased components feature library and the enterprise common parts feature library.
[0013] Furthermore, the common features stored in the other feature library include weight-reducing groove features and decorative groove features.
[0014] Furthermore, the process of building a general feature database is as follows:
[0015] In the CAD platform, select the geometric elements that constitute the common features, then establish data link parameters for each common feature data, output the user-defined feature data package, and then archive the user-defined feature data package to the PDM platform.
[0016] Furthermore, the data link parameters include code, drawing number, name, and schematic diagram address.
[0017] Furthermore, according to the design task book, when the matched common feature list is pushed to the CAD platform, the details are as follows:
[0018] When creating a design task book in the IDS platform, the IDS platform first structures the text content in the design task book, identifies the information in the design task book, extracts the elements in the design task book and matches them with the common feature database, and pushes the matched common feature list to the CAD platform.
[0019] Furthermore, the common feature list includes metadata of the common features and a geometric data storage path.
[0020] Furthermore, on the CAD platform, when the general feature database is called according to the general feature list for modeling, the specific steps are as follows:
[0021] A general feature calling program is embedded in the CAD platform. The general feature calling program calls the general feature database according to the general feature list pushed by the IDS platform, displays the pushed general feature data in the push library, and comprehensively displays all general feature data in the full library and updates it in real time; the general features required for structural design are selected in the push library and the full library, and are dragged to the target location for modeling and annotations are generated.
[0022] In a second aspect, a modeling system based on universal features of electronic device structure is provided, which is used to implement the modeling method based on universal features of electronic device structure as described in the first aspect, wherein the system includes a universal feature database module, a universal feature push module, and a universal feature call module;
[0023] The general feature database module is used to construct a general feature database, and the general feature database module includes a basic modeling module and a database storage module, wherein the basic modeling module is used to create a user-defined feature data package, and the database storage module is used to store the user-defined feature data package created by the basic modeling module;
[0024] The general feature push module matches a general feature data list according to the design task book and pushes the general feature data list to the general feature call module;
[0025] The general feature calling module calls the general feature database for modeling according to the general feature data list.
[0026] In a third aspect, a computer-readable storage medium is provided, storing a computer program, wherein when the computer program is executed by a processor, the steps described in the first aspect are implemented. The beneficial effects of the present invention are as follows:
[0027] Currently, structural design management is not granular enough, operating only at the component and whole-unit level, lacking management of these common features. Designers must repeatedly create common features and manually dimension them each time they create a model. The basic operations involved in modeling, such as points, lines, and surfaces, are cumbersome and prone to errors, resulting in inefficient structural design and insufficient standardization.
[0028] This application refines the granularity of electronic device structure R&D management from the traditional device and whole-piece levels to the feature level by building a universal feature database. Based on a multi-platform linkage mechanism, a design task book is created from the IDS platform and a feature list is pushed to the CAD platform. CAD then uses the universal feature database on the PDM platform to achieve efficient collaboration of design data. Designers can quickly call universal features directly through the CAD interface, avoiding repeated modeling and manual annotation, eliminating geometric errors and annotation omissions in manual modeling, improving design efficiency, and ensuring design quality.

[0034] The present invention will be further described below.
[0035] The present invention provides a method for modeling electronic equipment based on the general characteristics of the structure, which is operated in collaboration with the CAD platform (Computer-Aided Design), IDS (Intelligent Design System) platform, and PDM (Product Data Management) platform. The method architecture is as follows: Figure 1 As shown. The CAD platform software used in this embodiment is Creo; the IDS platform is an enterprise lean management platform; the PDM platform is a product R&D management platform developed based on Windchill; and the interactive module is implemented based on the Pro / Toolkit secondary development method. The CAD platform creates common features in different structural models, extracts them as UDF (User Defined Feature) data packages, and stores the UDF data packages on the PDM platform to complete the construction of the common feature database. The IDS platform is used to create a design task book, extract the key elements in the task book and match the common feature database, and push the matched common feature list to the common feature calling program of the CAD platform. The common feature calling program of the CAD platform calls the common feature database from the PDM platform based on the common feature list, quickly places the common features of the target into the corresponding three-dimensional structural model, and automatically brings out the dimension annotation to achieve rapid modeling.
[0036] The process of modeling method based on general characteristics of electronic equipment structure is as follows Figure 2 As shown, the following steps are included:
[0037] S10. Build a general feature database
[0038] The universal feature database is a system for storing universal feature data. Universal features are those that are identical or similar across different structural models. For example, if different electronic equipment modules are installed with the same component, the structural installation characteristics of that component are universal features. Based on the source and purpose of the features, the universal feature database consists of three logical sub-libraries: a purchased component feature library, a common enterprise parts feature library, and a miscellaneous feature library.
[0039] The purchased component feature library stores the installation interface features of purchased components used by the enterprise. Some purchased components may have multiple installation interface features based on different installation methods, such as front-mount and rear-mount features for electrical connectors. When establishing the installation features of purchased components, it is necessary to create multiple features simultaneously and distinguish them through suffixes.
[0040] The enterprise common parts feature library stores the repeated structural installation features of the enterprise's self-made parts. That is, when the enterprise's self-made parts, components or entire parts (such as a certain type of circuit board, etc.) are borrowed by different products, the structural installation features that need to be repeatedly established.
[0041] Other feature libraries store commonly used general features not covered by the above two feature libraries (purchased components feature library and enterprise general parts feature library), such as weight reduction groove features, decorative groove features, etc.
[0042] The process of building a general feature database is as follows:
[0043] S101. In 3D structural design software (such as SolidWorks, Creo, etc.), first select the geometric elements that constitute the common features, then establish standardized data link parameters for each common feature data, and finally output the UDF data package.
[0044] Data link parameters are used to achieve structured storage and efficient retrieval of common features in the database. The key parameters are as follows:
[0045] Code: unique identifier (e.g. 18200107339030), used for automatic system matching;
[0046] Drawing number: the associated engineering drawing document number (e.g. AL8.201.3535);
[0047] Name: a description of the feature's functionality (e.g., "honeycomb hole feature");
[0048] Schematic image address: The storage path of the feature thumbnail (for example, \\PDM\Features\Images\AL8_201_3535.jpg)
[0049] The UDF data package is created in the CAD platform. The UDF data package contains geometric data and bound metadata. The metadata includes code, drawing number, name, schematic diagram address, etc.
[0050] S102. Archive the UDF data package to the PDM platform
[0051] The archiving process is initiated through the integrated interface between CAD and PDM. The operator submits the work for review and approval. PDM performs review, approval, and approval operations, and PDM performs structured storage and archiving operations. Geometry data is stored in a dedicated file server, with a unique storage path identifier generated. Metadata is written to the central PDM database and bidirectionally indexed with the geometry data. The system automatically assigns an initial version number (e.g., A.2) and records the submission time, operator, and associated project information. Subsequent modifications require modification, revision, and review in PDM.
[0052] S20. According to the design task book, push the matched common feature list to the CAD platform
[0053] Establish a data link between the PDM platform and the IDS platform to implement data push functionality. When telecommunications personnel create a design task book on the IDS platform, the IDS platform first structures the text content, identifies key information such as the task book name, extracts key elements such as the task book code and drawing number, and matches them to the common feature database. Finally, the matched common feature list (including common feature metadata and the storage path of geometric data in PDM) is pushed to the common feature call program on the CAD platform for quick access by structural designers.
[0054] S30. On the CAD platform, call the general feature database for modeling based on the general feature list
[0055] A general feature call program is developed using 3D structural design software (such as SolidWorks and Creo). This embodiment uses the toolkit secondary development tool (other tools, such as Pro, can also be used for development) and embeds the developed general feature call program in Creo. Opening the general feature call program interface in Creo displays the general feature data pushed by the IDS platform in the push library, and the general feature database is fully displayed in the entire library and updated in real time. It has basic functions such as general feature selection, fuzzy search, and schematic image display. It also has a one-click placement function for general features, which allows you to drag and drop the call feature directly from the interface to the modeling area for quick placement.
[0056] Through the universal feature calling program embedded in the CAD platform, the universal features of the target can be quickly placed into the corresponding structural 3D model, and dimension annotations can be automatically brought out.
[0057] Common electronic device structure universal features include: electrical connector installation features, guide rail installation features, chassis installation features, weight reduction slot features, honeycomb hole features, etc. Through this application, universal features and dimension annotations can be called with one click, and universal features are automatically created by the system, avoiding the risk of errors in manual modeling. This embodiment uses a honeycomb hole feature as an example to describe how to implement a modeling method based on the universal features of electronic device structures after the universal feature database is built:
[0058] (1) Create a design task book in the IDS platform. The IDS platform identifies the common features corresponding to all devices in the design task book and pushes the common features to the common feature caller of the CAD platform.
[0059] (2) Start the general feature calling program interface in Creo to model. The general feature calling program interface is as follows: Figure 3 Select the common features required for structural design in the push library and the full library, and place them in the appropriate location. The drag and drop interface is as shown below. Figure 4 As shown, the system automatically generates comments (such as Figure 5 shown).
[0060] The present invention also provides a modeling system based on the universal features of electronic device structures, the system comprising a universal feature database module, a universal feature push module and a universal feature call module;
[0061] Among them, the general feature database module is used to construct a general feature database, and the general feature database module includes a basic modeling module and a database storage module; the basic modeling module is used to create a user-defined feature data package, and the user-defined feature data package contains geometric data and bound metadata, and the metadata includes coding, drawing number, name, schematic diagram address, etc.; the database storage module is used to store the user-defined feature data package created by the basic modeling module; the general feature database includes three logical sub-libraries: a purchased component feature library (storing the installation interface features of purchased parts), an enterprise general part feature library (storing the repeated installation features of the enterprise's self-made parts) and other feature libraries (storing commonly used general features not covered by the first two).
[0062] The general feature push module generates a general feature data list based on the design task book and pushes it to the general feature call module for quick access by structural designers. The general feature data list includes the metadata of the general feature and the storage path of the geometric data in PDM.
[0063] The general feature call module calls the general feature database for modeling based on the general feature data list. Embedded in the general feature call program, the module displays the general feature list pushed by the IDS platform in the push library and displays the general feature database across the entire library, updating it in real time. It offers basic functions such as general feature selection, fuzzy search, and schematic image display, as well as one-click general feature placement. Through the module, the target's general features can be quickly placed into the corresponding 3D structural model, automatically displaying dimension annotations.
[0064] The present invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the method for modeling based on the general characteristics of the electronic device structure.
